I don't disagree at all with your larger point but you can pretty well get addicted to anything. Physically: no, not at all. Physchologically: yes. Has anyone hit bottom and sucked dick for weed? Highly fucking doubt it. Actually, I support to some degree full decriminalization of all drugs with an appropriate and effective support and rehab based health system to go with it. No way any amount of health care for junkies is as expensive as the drug war and its mass incarceration.
I don't know the science of the addictive qualities (or lack) of marijunana... but I will say that anecdotally, I know LOTS of people who can't seem to function without marijuana. I know people who have. They may not have "needed" it.... but they certainly wanted it bad enough to do what they did. I'm not suggesting that weed (or shrooms, or LSD) is or isn't addictive. I think some science still needs to happen here.Has anyone hit bottom and sucked dick for weed? Highly fucking doubt it.
